Abstract

"PROCESSO E APARELHO PARA TRATAR UM MATERIAL DE CARGA EM PARTìCULAS FINAS, EM PARTICULAR CONTENDO METAL". A invenção refere-se a um processo para tratar um material de carga em partículas finas, em particular material de carga contendo metal, sendo que o material de carga e um gás de tratamento, em particular um gás redutor, são introduzidos em uma câmara de leito fluidizado 1, por exemplo, em um reator de leito fluidizado, de modo a formar um leito fluidizado. Neste processo, o gás de tratamento, depois de reação pelo menos parcial no leito fluidIzado 4, é descarregado do leito fluidizado e então, fora do leito fluidizado, é processado novamente pelo menos parcialmente, de preferência, oxidado, por uma reação química, em particular exotérmica, com um reagente, de preferência, com um agente oxidante gasoso e/ou líquido, sendo que a energia térmica desta reação é introduzida, pelo menos parcialmente, na câmara de leito fluidizado, em particular no leito fluidizado, ou é descarregada a partir dali. A invenção também se refere a uma unidade para a operação de um leito fluidizado.
